New OGF document published in the Information track: GFD-I.123 Title: Defining the Grid: A Roadmap for OGSA[TM] Standards Version 1.1 [Obsoletes GFD.53] Author/editors: C. Jordan, H. Kishimoto Abstract: The Open Grid Forum (OGF) has embraced the Open Grid Services Architecture (OGSA) as the blueprint for standards-based grid computing. "Open" refers to the process used to develop standards that achieve interoperability. "Grid" is concerned with the integration, virtualization, and management of services and resources in a distributed, heterogeneous environment. It is "service-oriented" because it delivers functionality as loosely coupled, interacting services aligned with industry-accepted Web service standards. The "architecture" defines the components, their organizations and interactions, and the design philosophy used. The purpose of this document is to provide an overview of the many interrelated recommendations and informational documents being produced by the OGSA and related working groups. Although, some documents are not OGSA specific, for example the "reference model," they have an important role within the OGSA concept and hence are explained in this document. This document also provides information regarding the intended completion dates of the documents in question, along with their dependencies on other OGSA and non-OGSA documents.
